I want you to Actually THINK about this question ......WHY would GOD have his SON carried and given birth by a SINNER? That absolutely makes NO SENSE! How do you reconcile your thinking with that?
It makes even less sense that God would promote remarriage, multiple partners, and children from at least 3 different parents living together.
That's basically what protestants aledge Christ family looked like.
THE BIBLE declares that
ALL [humans] have sinned and come short of the glory of God.
